Abstract :

We observed a rare case of the right persistent hypoglossal artery (PHA) in the posterior cranial fossa of a deceased 54–year–old male cadaver. The large–sized PHA originating from the cervical internal carotid artery passed through the hypoglossal canal and reached the posterior cranial fossa to anastomose with the basilar artery, accompanied by the hypoglossal nerve in the hypoglossal canal . In addition, the ipsilateral verteal artery and bilateral posterior communicating arteries were found to be hypoplastic. Here, we discuss the developmental mechanisms underlying the formation of the PHA and the spectrum of diseases related to its presence.
